Thank you!
Several games, like this one, are originally only available using a foreign (non-English) language. This one is Polish of origin.
That might be why many people don't know of them and that's also one of the reasons I'm remaking them into English versions: to make them wider available (and often improve them slightly too) :)
It's surprising how many good but non-English games there are from the late 80s up to the first half of the 90s retro era.
